Overview
The ATF1504ASV-15AU44 is a high-performance, electrically-erasable CPLD from Microchip Technology's ATF15xx series. It features 64 macrocells with up to 40 product terms each and operates within a 3.0V to 3.6V supply range. The device provides a maximum pin-to-pin delay of 15 ns and supports registered operation up to 76.9 MHz. It includes In-System Programmability (ISP) via JTAG, robust EEPROM technology rated for 10,000 program/erase cycles, and an industrial temperature range of -40°C to +85°C. The component is housed in a 44-TQFP package.
Feature Summary
- 64 Macrocells with flexible logic structure supporting D/T/Latch flip-flops and up to 40 expandable product terms per macrocell.
- In-System Programmability (ISP) via standard 4-pin JTAG interface compliant with IEEE Std. 1149.1.
- Advanced power management including automatic standby mode (ATF1504ASVL), pin-controlled power-down, and programmable pin-keeper circuits.
- Robust non-volatile EEPROM memory with 20-year data retention, 2000V ESD protection, and security fuse feature.
Applications
- Complex logic integration replacing multiple TTL, SSI, MSI, or classic PLDs.
- High-speed digital design requiring registered operation up to 77 MHz.
- PCI-compliant system interfaces and boundary-scan testing applications.
- State machine initialization utilizing built-in power-up reset features.
Procurement Notes
Verify the specific suffix 'AU44' corresponds to the 44-TQFP package and industrial temperature grade (-40°C to +85°C). Confirm that the 'V' designation indicates the 3.3V operating voltage variant. Ensure design tools support the ISP programming requirements via JTAG. Check for any recent Product Change Notifications (PCN) regarding packaging or marking updates.
Selection Notes
Select this model for designs requiring 64 macrocells and 32 user I/Os in a compact TQFP form factor. Choose the '-15' speed grade for maximum delays up to 15 ns. Consider the ASVL variant if automatic low-power standby modes are required. Ensure the design compiler supports the enhanced routing resources and cascade logic features for optimal utilization.
Part Context
This part belongs to the ATF1504ASV(L) family of high-density CPLDs. It shares architectural similarities with other ATF15xx devices but is distinguished by its 64-macrocell capacity and 3.3V operation. The 'AU44' suffix specifically denotes the 44-lead Thin Quad Flat Package (TQFP) configuration suitable for surface-mount assembly.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip's official compatibility guides or development tool selectors for potential cross-references within the ATF15xx family or newer generations.
